Niko: I promised to deal with you. I don't break promises. (Niko kicks him off the roof to his death)

(If Niko chooses to spare Ivan)

Niko: Get up. (Helps Ivan back onto roof) If Vlad wants you dead, you can't be all bad. Stay out of Hove Beach.

Ivan: Thank you. You won't regret this, man. I am outta here! Wanted to leave anyway, get away from all these people from back home. Get into the real America. You never gonna see me around here again. I owe you my life, man. You're a good man, you're a good man, thank you.

Other Dialogue

(Niko starts chasing Ivan)

Niko: Alright, Ivan, let's do this.

Niko: So you're the guy I'm meant to kill?

Niko: That prick Vlad making me kill this guy. Man!

Niko: Where you going to?

Niko: I wasn't sure about killing you when Vlad asked. Now I'm coming around to the idea.

Niko: I'm going to catch you, asshole.

Niko: Slow the fuck up, asshole.

Niko: Shit, you're starting to annoy me.

(Ivan escapes into construction site)

Ivan: Shit. Shit. Shit.

Ivan: Vlad's a bum, don't kill me for him.

Ivan: Stay the fuck away from me, I was set up!

Niko: You trying to Rob my cousin?

Ivan: Vlad's a bum, he set me up.

Niko: Man, I'm starting to sweat. Shit.

Niko: I thought everyone in this country was fat and slow.

Niko: Vlad don't like you no more, man.

Ivan: He's nothing in this town, don't do this for him.

Niko: You're a fast one, aren't you?

Ivan: I don't want no trouble with you!

(Niko corners Ivan)

Niko: You've ran out of roof, dickhead.

Niko: There ain't nowhere left for you to run.

Post mission phone call

(If Ivan is dead)

Niko: Ivan is dead. He came to a sticky end.

Vlad: Hey, you and your cousin's girlfriend should get together. She likes sticky finishes as well.

Niko: Fuck you. Say that to my face and I will break you.

(If Ivan is spared)

Niko: You won't be seeing your boyfriend Ivan no more. You going to miss him?

Vlad: No I'm not. I'm getting enough pussy at the moment. I tell you, is so much better if woman already have a man. Because you don't have to deal with all their shit all day. Take Mallorie, for example...

Niko: Fuck you. Say this to my face and I will break you.

Failing the mission

Ivan gets away

Niko: Hey, Vlad. I lost your boyfriend. He got away from me.

Vlad: I should have known you would screw this up. You are born loser, just like your cousin. Come see me sometime.
